Dear manoj dole, Here is your customized Science X Newsletter for May 9, 2024: Technology news Manganese sprinkled with iridium reduces need for rare metal without altering rate of green hydrogen production As the world is transitioning from a fossil fuel-based energy economy, many are betting on hydrogen to become the dominant energy currency. But producing "green" hydrogen without using fossil fuels is not yet possible on the scale we need because it requires iridium, a metal that is extremely rare. Robotic system feeds people with severe mobility limitations Cornell researchers have developed a robotic feeding system that uses computer vision, machine learning and multimodal sensing to safely feed people with severe mobility limitations, including those with spinal cord injuries, cerebral palsy and multiple sclerosis. ...

Dear manoj dole, Here is your customized Science X Newsletter for May 8, 2024: Technology news Video shows how swarms of miniature robots simultaneously clean up microplastics and microbes When old food packaging, discarded children's toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. AI and holography bring 3D augmented reality to regular glasses Researchers in the emerging field of spatial computing have developed a prototype augmented reality headset that uses holographic imaging to overlay full-color, 3D moving images on the lenses of what would appear to be an ordinary pair of glasses. Unlike the bulky headsets of present-day augmented reality systems, the new approach delivers a ...
